Sometimes eye doctors need only to make slight adjustments to lenses to help one's vision improve. Scientists on Mars Reconnaissance Orbiter's SHARAD (shallow radar) team asked spacecraft engineers to roll the orbiter about 25 degrees. By doing so, the radar team has managed to obtain even higher sensitivity from the instrument as it is shown in the "after" image. The team does not expect to perform these spacecraft rolls routinely but they will not miss the chance if one comes along to "see" these mysterious areas better than before.
